I can't find a program for screen sharing, really. I mean it:

  • Cross platform. Windows, Mac and Linux, not just Win+Mac.
  • Free. Not free for personal use only (TeamViewer), not free for 1 month, just free as in "freedom".
  • Works. Not cripled as Skype (Windows -> Linux screen sharing)
  • Simple. Grandma-level.

Are these demands too high?

Discord - no screen sharing yet (and may become shit like Skype if it stays closed and MS buys it then)

When you say "screen sharing", do you mean remote access? With one PC able to control the other, like TeamViewer? And file transfer?

If so, you cannot beat TightVNC. I have been using it for years and highly recommend it.

It is truly free and runs on Widnows, Mac & Linux.

It is also "granny simple", after you have set it up. Just configure her PC as a TightVNC server and yours as a client and you are done.

  • Actually it is enough for me just to show a screen

  • I may be wrong but you can't tell your ma: "yo, you're behind NAT, get white IP4 address or open some ports". If someone agrees to this quest I will spend 1h min to solve the problem.

Try Zoom.us. It's really simple, works well on Windows and Android for sure,I haven't tested on Linux. For more than 2 people, there's a 40 minute time limit on free plan. But it's awesome for one-on-one chatting/screensharing/drawing, etc. And its very lightweight. Worth checking out.
